AMD GPU linux drivers are (were?) a nightmare in general, and this includes iGPUs in their processors. Sadly, I don't have the impression that AMD is actively working on fixing this.
Just to make sure I'm not griping over something long fixed, I took a quick look and instantly found someone with a very similar issue to the one I ran into happening on a semi-recent kernel: https://community.amd.com/t5/pc-drivers-software/linux-amdgp...
It looks to me that if you want to have a working computer under Linux, it's worth the extra cost to avoid AMD.
